This article introduces how to use link in docker, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Create a dockerfile. In this article, the dockerfile is named Dockerfile_memcached (the file name can be defined at will):

# Memcached## VERSION 2.2FROM ubuntu:12.04MAINTAINER Marker.King # make sure the package repository is up to dateRUN echo "deb http://mirrors.aliyun.com/ubuntu precise main universe" > / etc/apt/sources.listRUN apt-get update# install memcachedRUN apt-get install-y memcached# Launch memcached when launching the containerENTRYPOINT ["memcached"] # run memcached as the daemon userUSER daemon# expose memcached portEXPOSE 11211

Build an image based on dockerfile:

$docker build-t memecached-

< Dockerfile_memcached 使用构建的镜像启动容器： $ docker run -d -name memcached_service memcached 根据镜像启动一个shell交互方式的容器，连接memcached服务，ubuntu_with_pip是我预先安装了pip的一个镜像： $ docker run -i -t -link memcached_service:db ubuntu_with_pip:12.04 /bin/bash 查看shell交互容器的环境变量： root@665f1bdc5913:/# envHOSTNAME=665f1bdc5913DB_NAME=/compassionate_pasteur/dbTERM=xtermDB_PORT=tcp://172.17.0.2:11211DB_PORT_11211_TCP_PROTO=tcpDB_PORT_11211_TCP_ADDR=172.17.0.2PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/binPWD=/SHLVL=1HOME=/DB_PORT_11211_TCP_PORT=11211DB_PORT_11211_TCP=tcp://172.17.0.2:11211container=lxc_=/usr/bin/env 安装python-memcached，并通过python测试是否能够正常使用： root@665f1bdc5913:/# pip install python-memcachedroot@665f1bdc5913:/# python>
